Attitude Determination and Control Summary This four-day course provides a detailed introduction to spacecraft attitude estimation and control. This course emphasizes many practical aspects of attitude control system design but with a solid theoretical foundation. The principles of operation and characteristics of attitude sensors and actuators are discussed. Spacecraft kinematics and dynamics are developed for use in control design and system simulation. Attitude determination methods are discussed in detail, including TRIAD, QUEST, Kalman filters. Sensor alignment and calibration is also covered. Environmental factors that affect pointing accuracy and attitude dynamics are presented. Pointing accuracy, stability (smear), and jitter definitions and analysis methods are presented. The various types of spacecraft pointing controllers and design, and analysis methods are presented. Students should have an engineering background including calculus and linear algebra. Sufficient background mathematics are presented in the course but is kept to the minimum necessary. Instructor Dr. Mark E. Pittelkau is an independent consultant. He was previously with the Applied Physics Laboratory, Orbital Sciences Corporation, CTA Space Systems, and Swales Aerospace. His early career at the Naval Surface Warfare Center involved target tracking, gun pointing control, and gun system calibration, and he has recently worked in target track fusion. His experience in satellite systems covers all phases of design and operation, including conceptual desig, implemen-tation, and testing of attitude control systems, attitude and orbit determination, and attitude sensor alignment and calibration, control-structure interaction analysis, stability and jitter analysis, and post-launch support. His current interests are precision attitude determination, attitude sensor calibration, orbit determination, and formation flying. Dr. Pittelkau earned the Bachelor's and Ph. D. degrees in Electrical Engineering at Tennessee Technological University and the Master's degree in EE at Virginia Polytechnic Institute and State University. What You Will Learn • Characteristics and principles of operation of attitude sensors and actuators. • Kinematics and dynamics. • Principles of time and coordinate systems. • Attitude determination methods, algorithms, and limits of performance; • Pointing accuracy, stability (smear), and jitter definitions and analysis methods. • Various types of pointing control systems and hardware necessary to meet particular control objectives. • Back-of-the envelope design techniques.
